Environmental Projects & Case Experience

For a national brownfields real estate developer at a Superfund site in the Philadelphia suburbs, remediation activities were implemented in accordance with an EPA Record of Decision. The project addressed complex contaminants, including ammonia and cyanide, and required extensive agency negotiation and stakeholder coordination within an active community setting.

Successful execution demonstrated Synergy’s ability to manage high-visibility remediation while maintaining regulatory alignment and community engagement.

At the North Penn Area 6 Superfund site, Synergy supported a potentially responsible party through the implementation of a detailed Remedial Action Work Plan involving soil and groundwater remediation.

Key activities included:

• Aquifer testing and hydrogeologic evaluation
• Baseline risk assessment demonstrating groundwater capture
• Regulatory approval of risk-based contaminant concentration levels

This work produced substantial cost savings that were incorporated into subsequent Consent Decrees governing multiple operating units at the site.

Synergy has provided long-term environmental services for a major petroleum client across New Jersey, Pennsylvania, and New York, supporting a portfolio of more than 170 retail gasoline stations.

Services have included:

• Environmental due diligence and permit transfers
• Remediation system design, installation, and operation
• Regulatory coordination with NJDEP, PADEP, and NYDEC
• Cost-to-closure development and scope definition
• Ongoing monitoring, reporting, and system maintenance

Funding strategies incorporated:

• Pollution legal liability coverage
• Insurance cost-cap structures
• State UST indemnification funding
• Escrow-based remediation financing

Remediation technologies deployed across the portfolio include air sparging, ozone injection, dual-phase extraction, soil vapor extraction, chemical treatment, and enhanced bioremediation.

Two-thirds of the New York portfolio sites have achieved regulatory closure.

For a regional gasoline distributor, Synergy performed due diligence, investigation, remediation, and regulatory oversight supporting the acquisition of more than 260 gasoline stations within a five-year period.

Aggressive remedial strategies emphasized:

• Achievement of regulatory closure and No Further Action status
• Use of available state funding programs, including PA USTIF
• Cost-efficient remediation system deployment
• Remote monitoring through proprietary management technology

These efforts generated significant cost savings while accelerating site closure timelines.

In East Petersburg, Synergy implemented an aggressive liquid-ring pump remediation system to address significant petroleum hydrocarbon groundwater impacts.

Regulatory closure was achieved in approximately 18 months, demonstrating the effectiveness of targeted system design, active performance monitoring, and decisive remedial implementation.

For a confidential energy client, Synergy completed Phase I ESAs for 107 facilities, including bulk storage terminals, fuel stations, and corporate properties.

Limited Phase II investigations were conducted at selected sites and included:

• Site-specific health and safety planning under federal HAZWOPER standards
• Utility clearance and soft-dig excavation
• Soil boring installation and groundwater sampling
• Laboratory analysis and technical reporting

All investigation activities were completed within accelerated transaction schedules while maintaining regulatory compliance and technical defensibility.

These representative projects reflect Synergy’s ability to deliver:

• Investigation and remediation under federal and state regulatory programs
• Portfolio-scale environmental management
• Insurance and funding strategy integration
• Risk-based closure and liability reduction
• Accelerated remediation timelines
• Defensible technical documentation for transactions and litigation

Experience spans industrial, municipal, petroleum, and redevelopment clients across the Mid-Atlantic, Northeast, and national project portfolios.

Synergy has provided independent Construction Quality Assurance (CQA) services for both landfill closure and Superfund site remediation projects, supporting successful project delivery under complex regulatory and environmental conditions. In each case, we served as the Owner’s trusted representative, confirming that construction activities were performed in accordance with approved design documents, technical specifications, and applicable regulatory requirements.

CQA services for landfill closure include oversight of earthwork, subgrade preparation, low permeability barrier installation, drainage layers, and final cover soils. Through proactive field monitoring, coordination with surveyors, and consistent documentation, our team verifies grades, material quality, and installation practices at critical construction milestones. The result is a compliant, durable landfill cap designed to protect human health and the environment while supporting long term site management objectives.

At Superfund sites, our CQA professionals support remediation and containment activities conducted under heightened regulatory oversight. Services include verification of site preparation, engineered containment layers, and protective soil systems, as well as coordination with construction teams and regulators to maintain compliance and continuity. Detailed field reporting, quality control reviews, and issue resolution helped manage risk and support timely progress.

Synergy delivers comprehensive CQA documentation and professional certification, providing clear, defensible records for regulatory approval and project closeout. Our involvement ensures construction quality, minimizes uncertainty, and provides protective remedies that meet long term performance goals.
